Kawasaki has further developed the KX250 for model year 2023. The result, according to Team Green, is the most powerful and refined KX250 ever, thanks to feedback from the Japanese engineers from the AMA Supercross and MX2 championship.
“With the most motocross titles of any manufacturer, Kawasaki has known what it takes to win for over 40 years,” reads Kawasaki’s 2023 KX250 press release. Strong words from Team Green that don’t lie, as long as you limit the stats to the AMA.
According to Kawasaki, the Kawasaki KX250 has been the reference in several competitions worldwide for years – a crucial bike in the KX range, which should take both national amateurs and professional MX2 riders to the top step of the podium.
For 2023, based on direct feedback from the AMA Supercross and MX2 championship, the Japanese engineers have further developed the new KX250. Okay, so we know that. What did they adjust?
The main changes are in the engine block. In the cylinder head, the intake valves have been made narrower (from 37 mm to 35.5 mm), which, in combination with a larger clearance at the valve seats, should ensure more efficient cylinder filling and better combustion for more top power.
In addition, the inlet is flatter and the upstream injector has been moved to the bottom of the inlet. The valves themselves have become smaller, which contributes to higher reliability.
A longer exhaust bend (457mm to 557mm) delivers more low and mid-range torque, while ignition timing has been retuned to match engine changes. There is also a longer first gear and the second gear has also been adjusted for a smoother transition.
The suspension was also further refined. The revised oil height in the front fork contributes to the optimized suspension characteristics. At the rear, the suspension is now equipped with a harder compression damping that contributes to suspension performance without compromising ride comfort.
Other chassis improvements include the 10mm wider rear tire for better traction. The footpegs have been widened by 5mm and moved back by 3mm for better grip and feel, making it easier to apply more pressure.
The mounting points of the footrests are made of aluminum, whereas in previous years they were made of steel. Together with other weight-saving measures in the suspension, these compensate for the extra weight of the wider rear tire.
The new KX250 will be at official Kawasaki Motocross dealers in mid-July. The price will be announced later.
